Given the general fascination with lush eyebrows lately, we can't say we're surprised. We all want Cara Delevingne's arches, and if we weren't blessed with a set of bold beauties at birth, we're compensating with brow tints, growth-stimulating serums and even hair transplant procedures, which are becoming increasingly popular.

Now, our obsession with arches is finally validated with factual evidence.

Participants were able to correctly identify 56 percent of the celebrities shown without eyes, but only 46 percent of the celebrities without eyebrows. The findings? Brows are more important than eyes if you want to make a lasting impression.
